I too replaced my differential fluid today. I have a friend who does mobile heavy equipment repair so I had him come today to help me change engine oil, grease, check brakes, and change dif fluid. Dan stuck his finger in the fill hole and said " this fluid looks new" I already had 5 gal. of Mobil synthetic 75W90 and had already decided to change any ways since I had no idea how many miles are on it. There is 136,000 on the coach so I'm assuming the fluid was original fill. There was maybe a tablespoons worth of shavings on the magnetic plug. Thanks to Bill for sharing your experience and giving us a "Heads up".
